Abstract:
A vehicle control system test facility(VCSTF) has been developed. The behavior of a distributed embedded control system was described and analyzed. Vehicle control hardware and operational environments were evaluated. Software architectures such as time-triggered,event-triggered,hybrid-triggered and other fault tolerant mechanisms for high reliability distributed embedded systems were tested. Multiple communication protocols can be evaluated on VCSTF and more reliable transmission is able to be achieved. A vehicle dynamic model,a motorway traffic model,and a driver model were developed for VCSTF.Simulations show these models comply with manufacturer and empirical data.VCSTF enables evaluation of novel software and hardware architectures for safety-critical automobile control systems,like the fault tolerant adaptive cruise control system(ACCS ) presented.
